A short income annuity as a bridge to delayed Social Security

The idea is simple. Instead of claiming Social Security at 62 or 65 because the bills need paying, you pay for the first few years of retirement from another source, wait, and then claim a larger monthly benefit later. One way to build that "another source" is a short income annuity that pays a fixed amount each month for a fixed number of years and then stops. When it ends, Social Security starts.

It is not the only way, and it is not right for most people. This post sets out how the idea works, the arithmetic, the criteria that favor it, the risks, the alternatives to price first and the point at which a financial planner is worth paying. Nothing here is a recommendation to buy; the figures are invented and the annuity price is an illustration.

How delaying Social Security works

Social Security retirement benefits depend on your earnings record and the age at which you claim. The Social Security Administration (SSA) sets a full retirement age, which is 67 for people born in 1960 or later. Claiming earlier than that age permanently reduces your monthly benefit. Waiting past it raises the benefit through delayed retirement credits of 8 percent a year, until age 70, after which waiting adds nothing. Confirm your own full retirement age and benefit estimates at ssa.gov, since they depend on your record and birth year.

Two features make the delay attractive to some households.

• The benefit is a lifetime income. It is paid for as long as you live, adjusted for inflation through cost-of-living adjustments. A bigger starting amount means bigger adjustments in dollars.
• It affects the survivor. When one spouse dies, the survivor generally keeps the larger of the two benefits. If the higher earner delayed, the survivor inherits that higher figure. The guide Social Security survivor benefits and the $255 death payment explains the survivor rules.

Delay has a price, which is that you must live on something else in the meantime. That is the gap the bridge fills.

What a bridge annuity is

A bridge annuity is a single premium immediate annuity (SPIA) structured to pay for a set number of years and then end. The industry calls the fixed-length design a term certain or period certain payout. You pay one premium, payments begin within about a year, and they stop after the chosen period. If you die during the period, a beneficiary typically receives the remaining payments; ask for the exact rule in the contract.

Compare that with the more familiar lifetime income annuity. A lifetime annuity is priced to pay as long as you live and therefore includes the cost of the long-lived. A bridge costs less per dollar of income because it has no lifetime promise, and it is more predictable, since it is a known number of payments.

Not every insurer offers a short-term period-certain payout, and the terms vary. Ask for written quotes from several companies. The annuity payout calculator gives a rough sense of what payments look like, and how annuity rates are set and why they move explains why prices move with interest rates.

The arithmetic of the idea

The following is hypothetical, with invented numbers.

Say Elena is 66 and has just retired. Her full retirement age is 67. Her estimated benefit at 67 is $2,500 a month. Using the 8 percent a year rule, her estimated benefit at 70 is $3,100 a month:

• three years of delay from 67 to 70 is 3 × 8 percent = 24 percent;
• $2,500 × 1.24 = $3,100.

She needs about $3,000 a month from other sources to cover essential spending. If she claims Social Security at 67, she covers most of that with her benefit. If she wants to claim at 70, she must fund $3,000 a month for the four years from 66 to 70.

• Four years is 48 months.
• 48 × $3,000 = $144,000 in total payments.

Say a bridge annuity were priced, purely for illustration, at $135,000 for $3,000 a month for 48 months. The $9,000 difference ($144,000 minus $135,000) represents the interest the insurer earns on the money while paying it out. That price is invented. A real quote could be higher or lower, and it will depend on the day she buys.

The break-even question

The delay costs her something up front. By waiting from 67 to 70 she gives up 36 months of $2,500, which is $90,000 ($2,500 × 36) of benefits she would have received. In exchange she receives $600 more each month for life ($3,100 minus $2,500), or $7,200 a year.

To see how long it takes for the higher benefit to catch up, divide: $90,000 ÷ $600 = 150 months, or 12.5 years after age 70, so about age 82.5. If she lives past that, she comes out ahead on this simple measure; if she does not, she comes out behind. The calculation ignores cost-of-living adjustments, taxes, the time value of money and what the surviving spouse gets, so treat it as a rough yardstick, not a forecast.

That yardstick shows why the choice is about longevity risk, not about getting the biggest check. A bridge is a way of buying protection against a long life by making the larger lifetime income available later.

The same example with a spouse

Now add Tom, Elena's husband, whose own benefit is $1,200 a month. When the first of them dies, the survivor generally keeps the larger benefit and the smaller one ends.

• If Elena claimed at 67 ($2,500) and died first, Tom would step up to $2,500.
• If Elena delayed to 70 ($3,100) and died first, Tom would step up to $3,100, which is $600 a month more ($3,100 minus $2,500).
• If Tom outlived her by ten years, that difference would be $600 × 120 months, or $72,000 in unadjusted dollars.

This is the strongest argument for a higher earner to delay: the extra income is not only hers, it is the household's protection against the survivor outliving the money. If Tom were the higher earner instead, the logic would run the other way, and it would be his claim that mattered. The numbers are invented, but the structure is how the rules work.

How to run the numbers yourself

1. Get your benefit estimates at several claiming ages from your SSA online account statement.
2. Write down your essential monthly spending and subtract any other income to find the monthly gap during the bridge years.
3. Multiply the gap by the number of months to get the total you would need to fund.
4. Ask for written quotes for a payout of that amount over that period, from at least three insurers, and compare the premium with the total.
5. Price the alternatives for the same stream: a ladder of Treasury securities or CDs and plain withdrawals.
6. Compute the break-even age as above, then repeat it for the survivor.
7. Decide how much margin you want if you live to 95 and if you do not.

Criteria that favor a bridge

A bridge tends to make more sense when several of these are true.

1. You have enough money to fund the gap but not an obvious way to do so safely. The years between retirement and the delayed claim are the years when a market drop does the most harm, because you are withdrawing from a smaller portfolio. A fixed payment removes that risk for those years.
2. You are the higher earner in a couple. Your delayed benefit becomes the survivor's benefit, so the extra monthly amount can last as long as either of you does.
3. You are in good health and your family tends to live long. The longer you live past the break-even age, the more the delay pays.
4. You do not need the lump sum for other purposes. The premium is spent; you cannot get it back.
5. You can still claim from other sources if plans change. Having other savings and flexibility reduces the cost of an error.
6. You prefer certainty about the next few years to flexibility. Some people simply sleep better knowing the gap is covered.

Criteria that argue against

1. Health problems or a short family history. If you may not live to the break-even age, claiming earlier may pay more in total, and a bridge locks in the cost of waiting.
2. A lower-earning spouse. If the survivor will rely on a lower benefit, the delay may matter less. The household's survivor picture drives it.
3. Limited savings. If the premium would use up most of what you have, the loss of flexibility is a risk of its own.
4. High expected medical or care costs. You may need the money elsewhere, and a short annuity cannot be reversed after the free-look period.
5. A lack of confidence about the insurer or the terms. Payments are only as good as the company paying them.

A decision list

Use this as a thinking aid, not an instruction.

• If you are the higher earner, your health is good, you have the savings to fund the gap and you want the largest lifetime benefit for you and a survivor, then a delayed claim is worth pricing, and a bridge is one way to pay for it.
• If your health is poor, or you will need the money for other things, then claiming earlier is usually worth considering, and a bridge adds little.
• If you can fund the gap by working part time, then the bridge may be unnecessary.
• If you can fund the gap from a bond ladder or cash, then compare costs before choosing an annuity.
• If you cannot decide, then pay a fee-only planner to model the cases, including the survivor, with your actual earnings record.

Alternatives to price first

A bond or CD ladder

A ladder of Treasury securities or bank certificates maturing one after another can produce a similar stream. Compare it with the annuity on cost, safety and flexibility. A ladder usually stays under your control, can be sold or redeemed in an emergency (sometimes at a loss), and leaves anything unspent to your heirs. An annuity gives you the discipline of a fixed payment, which some people value, and an insurer promise, rather than a government or bank one. Treasuries carry federal backing, while insurers carry the backing described below. The guide building an annuity ladder describes related staggering ideas, and a post on buying annuities in stages: a timing walkthrough over several years covers staged purchases.

Withdrawals from savings

Drawing down a portfolio for four years is the simplest alternative. It leaves the money invested and accessible but exposes you to market risk in precisely the years when a loss is hardest to recover from. How much that matters depends on your allocation and your cushion.

Part-time work

Earning even a modest amount for a few years reduces the amount you must fund. It may also delay the point at which you start drawing on savings. It is the least financial and often the most effective option for those who can do it.

A partial claim

Sometimes the answer is in between: claim a spouse's lower benefit earlier while the higher earner delays. The couple's combination matters more than either claim alone.

Risks of the bridge itself

• Inflation. A level payment for four years loses some purchasing power, though the effect is smaller over a short period than over thirty years. The post a flat annuity check and inflation: how purchasing power erodes shows the erosion over longer periods.
• Insurer risk. The payments depend on the insurer. State guaranty associations step in if an insurer is liquidated, within limits; according to NOLHGA, the common annuity limit is $250,000 in present value per person per insurer (as of June 1, 2025), with some states higher. A purchase well under that is easier to protect than one over it. Use the state guaranty association coverage lookup.
• Irreversibility. After a short free-look period, you generally cannot get the premium back. If you change your mind about delaying, you are left with the annuity.
• Rate timing. Prices depend on interest rates on the day you buy, and no one can forecast them.
• Taxes. For a non-qualified purchase, part of each payment is a return of your cost and part is taxable, using the exclusion ratio. If the money comes from an IRA, payments are generally fully taxable. A tax professional can show the effect on your bracket and on how much of your Social Security is taxed.
• Death during the bridge. Depending on the contract, a beneficiary may receive the remaining payments, or nothing. Know which.

When to consult a planner

The decision combines your earnings record, your spouse's, your savings, your health and tax rules. It rewards modeling, and a fee-only planner can run the cases for a flat or hourly fee. Bring your Social Security statement, your spending estimate and your account balances. If you are considering a large purchase, ask the planner to compare the annuity with the ladder and with simple withdrawals so you can see what each choice costs under good and poor outcomes.

Key takeaways

• A bridge annuity pays a fixed amount for a fixed number of years so Social Security can be claimed later, when delayed retirement credits of 8 percent a year (to age 70) raise the monthly benefit.
• A rough break-even for delaying from 67 to 70 is in the early 80s, but it ignores adjustments, taxes and the survivor benefit.
• The idea suits higher earners in good health with enough savings to fund the gap; it suits poorly when health is poor or the money may be needed elsewhere.
• Price a bond or CD ladder, withdrawals and part-time work before buying, and compare insurer risk with other risks.
• The premium is generally irreversible after the free-look period, so ask for written quotes and get a planner's view before committing.
